Subject: A question

Process context is schedulable but interrupt context is not. Why and
how?

Interrupt line can be shared by multiple interrupts or to avoid delay in
handling subsequent interrupts on single line - the handler has to be
quick enough. So we avoid scheduling out or sleeping inside the
interrupt handlers.

Adding...

Scheduling blocks. And if interrupt handler is blocked ( scheduled ) it
will lead to freeze.

Thanks.


Any examples I can look at?
